Question

The hydrogen bond is shortest in F - H ........F .

• A. F - H ........F
• B. False

Answer 1

The correct option is A

F - H ........F

A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons.
F is the most electronegative atom. Hence hydrogen bond is shortest in F - H ........F.
